sunroof rattles

I just bought my 2001 grandprix gt, I love the car but the sunroof rattles when closed. I have tried to find a service manual to but no luck.

Is there a way to adjust this sunroof to tighten it up?

thanks

I have the opposite problem, mine rattles when open. When closed, it doesn't make a sound. Anyone got any help?

My '98 GT GP sunroof sounds like it's scratching or popping when it's being opened--I saturated the track with wd 40 and for one day, it was fine. Also, it seems it is kind of crooked! AND the pop-up position doesn't work! When I push the button, it lifts and goes straight back instead of stopping at first position! I'm afraid it's going to break or something! Anyone got that one?
